.Application filed. November 7 i925. Serial No. 67,520.

The main objectof this invention is to provide an oil burning heating stove of the type using radiating elements or artificial fuels which is assembled as a complete unit with the fuel tank constituting a part thereof and one in which the fuel tank is protected so that the fuelis'not likely to become unduly heated. e

A further object is to provide a heating stove having these advantages which is quite compact and simple in structure and at the same time very efficient.

Objects pertaining to details and economies of construction and operation of my inveniton will definitely appear from the detailed description to follow.

' I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings forming a part of this application, in which:

Fig. 1 is a front perspective view of a heating stove embodying the features of my invention.

Fig, '2 is a rear perspective view.

Fig. 3 is a vertical section on a line corre sponding to line 3-3 of Figs. 1, 2 and 4.

Fig. 4 is a horizontal section on a line corresponding to line H of Figs. 1, 2 and 3, parts being broken away and sectioned to better illustrate structural details.

Fig. 5 is a fragmentary front elevation of the burner.

Referring to the drawings, I provide a casing comprising end walls 1 a top 2 and a bottom comprising sections 3 and 4. Dis posed vertically within the casing are front and rear partition walls 5 and 6. These walls are spaced and the front wall extends upwardly from the rear edge of the bottom section 4 while the rear partition wall 6 extends upwardly from the front edge of the bottom section 8. These partition walls provide a burner chamber 7 at the front and a tank'chamber 8 at the rear of the casing.-

The rear partition wall 6 has a rearwardly inclined top portion 9 constiuting a top for the chamber .8 while the front partition wall 5 has a rearwardly inclined top portion 10 for directing the air circulating. between the partitions rearwardly, the partitions terminatingin spaced relation to the top of the casing. r

A vertical flue plate 11 is disposed between the partition walls 5 and 6 coacting therewith to provide air circulating flues 12 and 18 which are open at the topand bottom for the free circulation of air; tank leis mounted in the chamber 8 which is provided with inner end walls 15. This tank is provided with a fillingplug 16, an air pump 1712\nd. a gauge 18150 that the liquid fuel may be delivered under pressure. A burner designated generally by the numeral 19 is mounted in the chamber 7 and has an upwardly flaring tip member 20'W1tl1 a plurality of series of slot-like jet orifices 21. The burner is generating burner. The details of the burner however, are not described as they form no part of this invention. y

Above the burner is a radiating element housing 23 and a rear, wall 24, the top being spaced from thetop of the casing providing an air chamber 25 above. the'housing' communicating with thespace to which the circulating flues described deliver. The rear .wall 24is spaced fromthe wall 5 providing an insulating chamber26. v,The radiatingelements 27 are arranged upon the burner within this housing. A hearth plate 28 extends forwardly from the lower ends of the burner. The burner chamber below this hearth plateis provided with afront wall 29-ha'ving a removable panel 30 with air inlet openings 31 therein. The burner chamber is thus closed from any direct connection with the fuel tank chamber, the circulating flues preventing the' tank from becoming unduly heated.

The'air space 26 also serves as an insulat ing space between the radiating elements and the fuel tank chamber. 1

-My improved heating stove is highly etfi cient and at the same time is quite compact and may be moved aboutor transported as a unit, that is, the fuel tankas a part of the structure. A drip pan 32 is preferably provided below the fuel tank.

I have illustrated and described'my improvements in an embodiment which I have found very practical. I have not attempted to illustrate or describe certain embodiments or adaptations which I contemplate asI believe the disclosure made will enable the embodiment or adaptation as maybedesired.
